Materials Data on CeNiC2 by Materials Project
CeNiC2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Ce4+ is bonded in a 8-coordinate geometry to eight equivalent C3- atoms. There are four shorter (2.70 Å) and four longer (2.77 Å) Ce–C bond lengths. Ni2+ is bonded in a 4-coordinate geometry to four equivalent C3- atoms. There is two shorter (1.94 Å) and two longer (2.00 Å) Ni–C bond length. C3- is bonded in a 7-coordinate geometry to four equivalent Ce4+, two equivalent Ni2+, and one C3- atom. The C–C bond length is 1.39 Å.
